first important part for the ml bindings merge:

make appletInterface more generic it could work with QML too
simplejavascriptapplet inherits from an abstract ckass that provides just the virtuals of functions needed by appletinterface so a different scriptengine implementation can be used as well.

The behaviour of the current js bindings should be completely unchanged.
